How to remove spaces from an array in php, WordPress

To remove spaces from array elements in PHP, you can use the array_map function along with trim(). In WordPress, this works the same way.

Example:

// Original array
$array = ['  element1  ', 'element2 ', ' element3'];

// Remove spaces from each array element
$trimmed_array = array_map('trim', $array);

// Output the result
print_r($trimmed_array);

This code applies the trim() function to all elements of the array, removing spaces from the beginning and end of each element.

In WordPress, you can use this in places like functions.php or in plugins.
